(CNN) Should Joe Biden win the upcoming US presidential election, his first and overwhelming foreign policy challenge will be winning back the trust of America's allies. European allies in particular will be hoping that if he does become president, Biden swiftly makes a convincing case that President Donald Trump's four years in office were an anti-democratic aberration that can never be repeated. The Middle East will be a challenging environment for a President Biden to win friends. But it is in China that the next president will face a defining foreign policy challenge -- and where understanding allies will be most indispensable. Chinese President Xi has perhaps more at stake with a Biden presidency than any other world leader.
